WHAT IS SIP?
Session Initiation Protocol (SIP) is a fully scalable business voice service that includes a broad assortment of state-of-the-art IP features, and significantly reduces the cost and complexity of your voice network.
SIP trunking is a Voice over Internet Protocol (VoIP) service based on a secure connection. For many businesses, SIP is more affordable than utilizing a primary rate interface (PRI) connection. By moving to a SIP trunking service, businesses can save on both transport and long distance services. SIP trunking includes a broad assortment of next-generation IP features, which reduce both cost and complexity. It is also fully scalable to serve businesses of all sizes.
